I have a product that has two different build, one for iPhone, and another one for iPad.
Is it possible to unlock features via In-App purchase in both with make the playement once from one of them?

You cannot use the same ID, howerver, you can manage information about which purchases have been made by which users on your own server, and update that information every time a user buys something. You just have to check on that server which purchases have been made.
